Screen Projection Control Switching for Dual-Screen Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen projection systems lack flexibility in operation, allowing users to control either the target screen or the virtual screen but not simultaneously, thereby affecting work efficiency.
Innovation Solution
A method and apparatus that enable switching the control object of an external control device from the target screen to a virtual screen and setting the control object of the electronic device as the target screen, allowing simultaneous control of both screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control object of the external control device is fixed to the target screen, then the control relationship is simple and stable, but the user cannot control both the target screen and virtual screen simultaneously
Solution Approach 1:
The patent implements dynamic switching of the control object between the target screen and the virtual screen based on user needs. The external control device can be configured to control either the target screen or the virtual screen through switching instructions, allowing the control relationship to adapt to different operational scenarios rather than being fixed to one target.
Solution Approach 2:
The external control device is designed with multi-functionality to control both the target screen and the virtual screen. By incorporating a switching mechanism that allows the external control device to change its control target, the system enables a single control device to serve multiple control needs, enhancing its universality and flexibility.
2Adaptability or versatility
If the control object switches between target screen and virtual screen, then the user can control both screens, but the control relationship becomes more complex
Solution Approach 1:
The patent introduces a control switching instruction as an intermediary mechanism that mediates between the user's control needs and the control object. This switching instruction acts as a mediator to change the control relationship from the external control device to either the target screen or the virtual screen, simplifying the user's operation by providing a clear switching mechanism rather than requiring complex direct control configurations.
3Adaptability or versatility
If the external control device controls the virtual screen, then the virtual screen can be operated externally, but the target screen control may be affected
Solution Approach 1:
The patent implements a dynamic control mechanism where the external control device can switch its control target between the target screen and the virtual screen. When controlling the virtual screen, the system dynamically adjusts the control relationship to ensure that the virtual screen receives external control inputs while the target screen maintains its own control independence, thus maintaining control stability for both screens through dynamic configuration.

AI summary
The disclosure relates to a screen projection method, a screen projection apparatus, an electronic device, a storage medium, and a chip. The method is capable of, in response to receiving a screen projection instruction triggered by a user, determining (S201) a virtual screen to be projected according to a target interface displayed by a target screen of the electronic device; projecting (S202) the virtual screen to a target screen projecting device; and, in response to receiving a first control switching instruction triggered by the user, switching (S203) a control object of the external control device from the target screen to the virtual screen and setting a control object of a control component of the electronic device as the target screen.
